Opened my pool late this year and was lucky that it hadn’t bloomed.
Whilst trying to shock it with 7litres of 9.6% bleach I found my Aquachek strips showed 5ppm total and 0ppm free chlorine.
So I have added what should have been enough to mustard shock my 48 cubic meter pool.
Still my test strips show the same 5ppm total and 0ppm free chlorine.
At what point do I stop adding shock, could my free chlorine pad on the strips be being bleached out white (the other all show a colour as normal) ?
Many thanks
